'Charnley Forest' turns out to be Coticule

**Oldengaerde** · 03-08-2009, 05:32 PM

Today I finally came round to clean a veined dark greenish 185mm oil stone in a wooden box that I thought was a a Charnley Forest. I bought it cheap as chips, but it was very, very dirty with loads of grease and workshop grime. Cleaning turned out to be relatively easy though and underneath the smudge appeared what I now believe is a fine vintage coticule. I haven't honed on it, but lapping indicated it is one of the thougher varieties. There are quite a number of veins-turned-into-cracks that can't be felt, but if and how they impair honing remains to be seen.

Sweet coticule. I'm sure you'll get no trouble from the veins in the stone when honing. Isn't it great to lap and reveal what vintage stones have to offer?

Lovely stone ! How thick is it ? Please report how it performs after you use it for awhile.

Wow that's a beautiful looking rock....

Please feed back about how the hone works..

Very pretty. You're going to have to either be careful about keeping your blade perfectly flat or else do a heck of a lot of beveling on the edges of that rock.

That's beautiful! I'd be pleased with that kind of surprise.

You bet I am! Very! Not that another Charnley wouldn't have been nice, but this Coticule is beautiful, and it's my first patterned vintage one.

Yes, the edges are a challenge

I think I'm going to bevel them considerably, but I didn't want to do it just yet. I felt bad enough already for removing lots of material to correct the cupping...

The height above the wood is just 5mm (sorry across the waters, this guy prefers SI units

). Total height, stone and socket, is 24mm. It is difficult to estimate how deep the stone is set. Weight suggests it could be quite a bit.

Chances are the glue that is holding the stone is water soluble. I got an old vintage stone loose once by soaking it under water for a few days. ChrisL has gotten a stone un-glued on a very low heat in the oven.

I would get it out of the base if it was mine to see what the rest of it looked like. It could be a natural with a BBW underneath.
